New dad Scott says of his son, "I fall so much more in love with this kid every day. I can't imagine how much more in love with him I'm going to be by the time he's 5 or 10 or 20!"

As for the diaper changes, Scott admits he hasn't been too involved, telling the mag, "I haven't been too hands-on with the changing of the diapers. ... I've spectated and given some support!"

Kourtney delivered a healthy baby boy at a Los Angeles hospital on the morning of Dec. 14. The bundle of joy weighed in at 7 pounds, 6 ounces and is 19.5 inches. Kourtney says of the labor, "It was surprisingly easy and just an incredible experience. I always thought your first is supposed to be really hard, but it was easy."

The couple named their new son Mason Dash Disick, his middle name being the same as the family's boutique.

So is Kourtney planning for a second baby? The reality star responds, "Right now I'm obsessed with Mason and want to give him all my time. But being with him has definitely made me think about having another one! Kim and I are 18 months apart. Growing up, we did everything together. It would be nice for Mason to have a little brother or sister that many months apart too."
